To CLZ 1,071,077?, t nw/y concern,.-

Be it known that I, CHARLES E. C. EDEY, a citizen of the United States,residing at Tacoma, in the county of Pierce and State of XVashington,have invented cert-ain new and useful Improvements in Car-Couplers; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the sanne.

My invention relates to improvements in car-couplers, and moreparticularly to the Janney type, which employ knuckles provided with apivoted jaw; and it consists in a coupler having a pivoted jaw, the saidjaw having' a rearwardly-extending arm adapted to be locked in thecoupler, and means upon the said arm for removing the strain from thepivot-pin of the coupler and preventing the jaw from rocking.

lt also consists of certain other novel constructions, combinations, andarrangements of parts, as Will be hereinafter fully described andspecifically claimed.

Figure 1 represents a horizontal section through the said coupler, thelockingjaw being closed. Fig. 2 represents asimilar view, the lockingpivoted jaw being open. Fig. 3 represents a perspective view of the saidjaw, and Fig. 4 represents a detail view showing the means forstrengthening the said jaw when in its closed position.

l iu the drawings represents the draw-head of the coupler, 2 a pivotedor locking jaw, and 3 a pivot-pin.

In couplers of this type there is a great deal of strain brought to bearon the pivotpin of the locking-jaw, and it is very'desirable to providemeans in the draw-head which will serve to remove a great deal of strainbrought to bear upon the said pivotpin.

With this object in view my invention is designed to so form the pivotedlocking-jaw of the portion of the draw-head in which it is mounted thatthe parts will be more or less interlocked when closed, and strengthwill thus be aiorded to the structure. The pivoted jaw 2 is providedupon its rearwardly extending arm or tailpiece 4 with a projection orlug 5, preferably cast integral therewith. This projection 5 is adaptedto engage a correspondinglyeshaped socket or recess 6,

formed upon the inner surface of the wall of the draw-head. Theprojection 5 is formed thicker and wider at its outer end 7 than it isat its inner end 8, so that when it tits into the corresponding socket 6it will form a dovetail joint with lthe wall of the coupler and be -ableto withstand shocks of great It will be seen `that this device may beapplied to any coupler of. the ordinary Janney pattern and that theprojection 5 will not only be shouldered against the abutting face 9 ot'the socket 6, but, because of its dovetail shape, it will prevent to agreat eX- tent any rocking m'otion of the pivoted jaw upon itspivot-pin. So, also, the projection 5, because of its dover-ailconnection with the draw-head, will sustain a pulling strain as Well asa pushing strain.

It will be observed that the parts are so constructed that thestrengthening -joint formed between the projection 5 and the socket 6does not in any way interfere with the use and usual manipulation of thepivoted jaw in the operation of coupling and uncoupling two couplers. Itdesired, the projection 5 may be made separate from the pivoted jaw andbe bolted or riveted thereto. The socket 6 also may be formed in a piecewhich is sep'- arate from the draw-head and may be firmly Secured byrivets, bolts, or welded to the said draw-head without departing fromthe spirit of my invention.

Having now described my invention, what I claim as new, and desire tosecure byLetters Patent, is-

1. A carcoupler, comprising a suitable draw-head having a socket formedin one of its walls which is larger at the rear end than at the front,the said recess tapering from rea'r to front, a pivoted locking jawmounted in said draw-head, a tapering strengthening projection formedupon said pivoted jaw adapted to fit into the socket. in thedrawheadwhen the jaw is closed, whereby strain will be removed from thepivot-pin of the jaw, substantially as described.

2. A car-coupler, comprising a draw-head, a pivoted jaw mounted therein,a rearwardlyextending locking arm on the said jaw, a strengthening wedgeshaped projection j formed upon the said jaw adapted to tit in acorrespondingly-shaped socket formed in one of the Walls of thedraw-head, the said socket having a rea-r abutting face, and upper andlower limiting-farces, so that the projection on the pivot-ed jaw willbe dovetailed therein, and so as t-o guard age-inst front and backpressure and any rocking of the pivoted jaw upon its pivot-pin, substantially as described.
